Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to and benefits of Chinese patent application No. 202310808972.2, filed with China National Intellectual Property Administration on July 3, 2023, the entire content of which incorporated herein by reference. FIELD The present disclosure relates to the field of electrical appliance control technologies, and more particularly, to a cooking appliance and a control method for the cooking appliance. BACKGROUND A moisture control function is almost a standard feature in many cooking appliances, such as a professional commercial steam oven. However, the moisture control function advertised by the cooking appliance with this capability is primarily mainly achieved by generating steam through a steam generator for humidification, while dehumidification is accomplished through corresponding exhaust vents. However, a small size of these exhaust vents results in limited dehumidification capacity and slow dehumidification speed, which fails to meet the requirements for chamber humidity in different cooking scenarios or for different food ingredients. Consequently, the cooking performance of the cooking appliance is unable to be guaranteed. SUMMARY Embodiments of the present disclosure provide a cooking appliance and a control method for the cooking appliance. The embodiments of the present disclosure provide a cooking appliance. The cooking appliance comprises: a cabinet, a cabinet door, and a dehumidification device. The cabinet has an opening. The cabinet door is disposed at the cabinet in an openable and closable manner. The cabinet door is configured to seal the opening when the cabinet door is closed. The dehumidification device is configured to push the cabinet door open in response to a door-opening control instruction.

In some embodiments, the operation parameter comprises at least one of a cooking duration, a cooking temperature, or a cooking humidity. In some embodiments, the operation parameter comprises a cooking duration. The control device is further configured to generate the door-opening control instruction in response to the cooking duration reaching a predetermined duration. When the cooking duration reaches the predetermined duration, the cooking humidity inside the cabinet is greater than a predetermined humidity. In some embodiments, the cooking appliance further comprises a temperature sensor configured to collect a cooking temperature inside the cabinet. The operation parameter comprises the cooking temperature. The control device is further configured to generate the door-opening control instruction in response to the cooking temperature reaching a predetermined temperature. When the cooking temperature reaches the predetermined temperature, the cooking humidity inside the cabinet is greater than a predetermined humidity. In some embodiments, the cooking appliance further comprises a humidity sensor configured to collect the cooking humidity inside the cabinet. The operation parameter comprises the cooking humidity. The control device is further configured to generate the door-opening control instruction in response to the cooking humidity reaching a predetermined humidity. In some embodiments, the cooking appliance further comprises a heating device. The control device is further configured to control the heating device to perform preheating. The dehumidification device is configured not to respond to the door-opening control instruction within a predetermined duration subsequent to start of the preheating. In some embodiments, the dehumidification device comprises a motor and a push rod. The motor is configured to drive, in response to the door-opening control instruction, the push rod to move to push the cabinet door open. In some embodiments, the cabinet door is connected to the cabinet via a hinge structure. The motor is configured to drive, in response to the door-opening control instruction, the push rod to move in a direction toward the cabinet door, to push the cabinet door open. The operation parameter comprises a dehumidification duration. The control device is further configured to generate, in response to the dehumidification duration being greater than a predetermined dehumidification duration, a door-closing control instruction. The motor is further configured to drive, in response to the door-closing control instruction, the push rod to move in a direction away from the cabinet door. The cabinet door is closed under drive of the hinge structure. In some embodiments, the push rod is connected to the cabinet door.
